Twistsonics: engineering acoustic topological textures in moire sound lattices
Wen-Yu Wang, Shuai Liu, Xiang-Yuan Xu +4
Moire superlattices formed by twisting periodic systems provide a powerful platform for emergent topological phenomena, but their use for programming real-space topology in acousti…

Acoustic helical dichroism enhanced by chiral quasi-bound states in the continuum
Qing Tong, Tong Fu, Yuqiong Cheng +1
Acoustic helical dichroism (HD) arises from the interaction between vortex beams carrying orbital angular momentum (OAM) and chiral media, yet such chiral sound-matter interactions…
